Just my opinion

we have looked all over for this oil. no one has it and the prices that they would have been are much higher than this price. got it very quickly and was very blessed by finding it and the price.

Rosella seems to be the gold standard for diesel engines. From my way of thinking, the T-6 formula has been tuned for maximum protection for diesel engines. The 5W-40 rating would suggest it has been developed as an all season oil. As you can tell by my vagueness, I cannot prove any of these points, it is just my opinion.

A very good motor oil for my motorcycles. Inexpensive compared to other top end brands. Whenever I change my oil (about 3k to 5k miles), the old oil is very clean and I have never seen any metal particulates. Im sure other oils do the same job but the price sets Rotella apart.

This is a knock on Walmart not Shell. The oil is great and it's all I use in my diesel engines. HOWEVER, Walmart sent me three (yes three) OPENED/USED gallons of oil. They all three were tied in trash bags and weighed 6.75,7%267.5 lbs respectively. What are you trying to pull Walmart???? RIDICULOUS!!!!

The oil is outstanding!! Your packaging is horrific!! Three separate 1 gal containers in a large box no packaging the box was torn open!! I am not sure what training you give your technician on boxing but they need to be retrained!! Again oil awesome but packaging is disappointing

[This review was collected as part of a promotion.] I do my own work on my diesel vehicles and only run diesel oil made for diesel engines. Shell / Rotella is a great fit for my vehicles and meets the specifications from the vehicle manufacture - Mercedes Benz. I will also investigate to see if this will work in my diesel tractor.

i know this is oil for diesel engines, but a lot of owners with turbo gasoline cars such as Subaru WRX and STi's use it for their cars. I picked it up because I drive a Nissan 300ZX and fellow 300ZX drivers on forums were recommending this oil over Royal Purple, AMSoil, Mobil1, and all other full synthetic oil. I tried it out because Royal Purple was burning to quickly and after driving a while, my oil dipstick still shows clean oil on it!

I use this oil in the last 3 Goldwing motorcycles I have owned. I change oil every 5,000 miles. The oil has at least 5,000 miles remaining on it when drained. I am sure I could go another 5,000, but it has become a habit to change at those intervals.

Shell Rotella T6 Synthetic Diesel Oil is the Absolute Best available for your Diesel Vehicle in my humble opinion. It’s 100% Synthetic (Not a Synthetic Blend) with an Additive Package to help extend the life of your engine. I’ve been using Shell Rotella now for over twenty years.
